岩体承受的压应力一般随深度而增加。然而,增加的值视各种因素而不同。影响原岩应力的因素包括覆盖层重量、局部和区域地质构造、构造应力、残余应力和热应力。这些因素与原岩应力之间关系的复杂性往往妨碍岩石应力的可靠估算。此外,应力不能直接测量,所以岩石应力测量技术依赖于位移、应变或变形测量。应着重强调的是岩石应力测量的各种方法是相互补充的,视特定用途各具优缺点。
The compressive stress of rock mass generally increases with depth. However, the added value varies depending on various factors. Factors that affect the stress of the original rock include the weight of the overburden, local and regional geological structure, tectonic stress, residual stress and thermal stress. The complexity of the relationship between these factors and the stress of the original rock often precludes a reliable estimate of rock stress. In addition, stress can not be measured directly, so rock stress measurement techniques rely on displacement, strain or deformation measurements. It should be emphasized that various methods of rock stress measurement complement each other, depending on the specific application.
